UNITED STA ss PATE ANTHONY PETEB DOELL, 0F MINNEAPOLIS, MINNESOTA.

To all it may concern:

Be it known that I, ANTHONY PETER,

DOELL, a citizen of the United States residing at Minneapolis, in the county of ennepin and State of Minnesota, have invented a new and useful Draft-Producing Device, of which the following is a specification.

y invention relates to improvements in draft producing devices.

Its object is to provide a simple anddurable device for accelerating thedraft in a chimney. g a j A further ob'ect is to provide a knockdown device 0 readily passed through a pipe-hole in a chimney andquickly and easily assembled therein.

A further object is to provide aihezitradiating attachment for, fines, together w1th a pan designed to be p1aced,therebeneath,sa1d

pan providing a self-cleaning false bottom in the flueand also serving todirectheated attach taryperspective view ofa fi gases, against the membersof said radiating Inent, upon their entry into the flue.

\Vith the foregoing and other objects in view, which williappear in the following description, the invention residesin the novel com inationand arrangement of parts and in the details of construction hereinafterdescribed and claimed. y

In the drawings, Figure 1 is a fra enue or chimney containing a device embodying my invention; Fi 2 is a plan view in detail of the hanger; Fig. 3 is a rspective view in detail showing one oi' the radiating plates; Fig. 4 is an elevation in detail of the clip and Fig. 5 is a perspective view showing, in detail, the members of the deflecting pan.

Referring to the drawings, it will be seen that my improved device comprises a hanger A, radiating plates B, a connecting clip C for said plates and a deflecting pan D, said parts being designed to be inserted in a pipe- 0 ening in a fine and assembled therein.

e hanger A com rises two crossed metallic bars 10 pivotally connected at their intersection. The tips 11 of said bars are pointed or otherwise reduced so as to be readily shaped to fit and engage the walls of a flue. These bars are formed with perforations 12 in each branch thereof for purposes as will hereinafter appear. The radiating plates B are formed of metal or other material adapted to readily conduct and radiate heat. Each plate is formed with per- Specification of Letters Patent.

, in the upper margin thereof, through which a wire 14 may be threaded, as shown. A perforation 15 .is also formed in the lowertmargin of each plate. The clip C includes a metallic disk-like bod portion 16 with a plurality of radial yielding jaws 17 thereon. Said jaws are designed to receive and grip the lower margins of the plates B and rigidly secure the same. Openings 18 are, formedin said jaws to receive locking pins 19, which are passed through two or more of the jaws 17 and through the perforations 15in the plates B. The pan D comprises two curved sheet metal members 20 and 21. Each member has a marginal bead 22 containing a reinforcing wire 23 extending beyond either end thereof. End portions 24- of the member. 20 are turned upon the body thereof to form slides 25 for the ends of thecompanion section.

In assembling my device within a flue, the members of the pan D are telescoped so as to pass through a pipe-opening therein. Said members are extended within the flue and the pan hung therein as shown in Fig. 1. I prefer to increasethe curvature of the pan, by force, within the flue so that the resiliency thereof will operate to firmly enforations 13 gage the projecting endsof the rods 23 with j the wallsof the flue.

.said ends It will be noted that of said rods in addition to supporting the pan D, act as spacers and form openings 26.(Fig. 1) between the ends of said pan and adjacent walls ofthe flue. The folded hanger A is inserted through the pipe-opening in the flue and thereafter opened, the ends thereof being caught in the corners of the fine. A plate B, with a Wire 14 threaded therein, is passed through the pipe-opening, the ends of said wires being inserted in perforations 12 in a hanger arm and bent at their tips to secure the plate to said arm. The remaining plates are similarly suspended from the remaining arms of the hanger A and the clip C is thereafter aflixed to said plates as described.

The pan D substantially cuts off the usual cleanput well beneath the pipe-opening, yet permits the escape of cinders and the like thereto, the same beingcleanly swept from the curved surface of the pan by the incoming gases from a stove or other device. The plates B divide a section of the flue into segmental compartments. This construction, together with the deflecting and distributing pan Dprovides for applying the maxithe'draft within a flue. It provides for the attainment of,increaseddrafts, at small expense and without damage to or alteration of aflue orchimney.

' ters Patent is:

Changes in the specific form of my invention, as herein disclosed, may be made within thescope of what .is claimed without departing from the spirit of my invention.

Having described my invention what I claim as new and desire to protect by LetlQA device of the-class described, comprising the foilowing parts, each being capable of being passed through a pipe-opening in afflueza folding hanger designed to be supported by "engagement with the-walls of the flue, heat radiating platesiadapted to be carried by said hanger and a pan including telescopically connected-members, said pan being designedto be hung in the flue beneath said plates and direct heated gases thereagainst. v

I 2.; In a device of the class described, a hanger comprising crossed members, the ends-thereof being designed to engage the walls of a flue, heat radiating plates adapted to be suspended from said hanger, opposite the pipe-opening in the flue, and arranged to divide a section of the flue into segmental compartments and a pan designed to be hung in theflue'beneath said plates, said pan being. adapted to direct heated gases into all of said compartments and formed to provide an opening into the clean-out chamber of the flue for the escape of cinders or the like.

3. A device of the class described, comprising the following parts, each capable of being passed through a pipe-opening in a flue: a folding hanger designed to be supported by engagement with the walls of the flue, heat radiating plates adapted to be suspended from said hanger, opposite said pipeopening, a clip to join said plates at the lower edges thereof and a pan including telescopically connected members, said pan being designed to be hung beneath said plates and direct heated gases there-against. 4. In a device of the class described a hanger comprising crossed members, the ends thereof being designed to engage the walls of a flue, a heat retaining element adapted to be carried by said hanger, opposite a pipe-opening therein, and arranged to divide a section of the flue into compartments and a heat distributing pan designed to be hung in the flue beneath said heat retaining element.

5. In a device of the class desribed the combination with a flue of a hanger designed to rest in the flue, radiating devices carried by said hanger in position to contact with heated gases entering the flue through a pipe-opening therein and a pan designed to be hung in the flue beneath said radiating devices.

6. In "a device of the class described, a plurality of heat radiating members adapted to be hung in a flue opposite a pipe-opening therein and a pan designed to be hung in the flue beneath said members, said pan being curved as and for the purposes described.

In testimony whereof I have signed my name to this specification.

ANTHONY PETER DOELL.
